With support from the Muskwa-Kechika Trust Fund as a Seed Grant, Dr. Paul Sanborn carried out a pilot study of soils in relation to prescribed burning in the Northern Rocky Mountains, in collaboration with Perry Grilz, then a Range Officer in the Ministry of Forests. Sanborn and Grilz conducted 3 days of field work in July 2001. Sanborn wanted to test the utility of plant-derived opal (phytoliths) as a soil indicator of vegetation history, in the hope of distinguishing natural grasslands from those created by anthropogenic burning.
EP 660 was a conventional silvicultural trial established in 1967 which involved single species plantings of lodgepole pine (Pl), white spruce (Sw), and Douglas-fir (Fd) at different spacings. Three installations were established in the Prince George - Vanderhoof area: Buckhorn Ridge, Bobtail Road, and Chilco Creek.

Forest soil sulphur research was a continuing interest for Dr. Paul Sanborn for more than 30 years, beginning at UBC in the mid-1980s when he took a graduate course in Forest Soils from Dr. Tim Ballard. Among the things that he learned was that soils in much of BC were deficient in sulphur (S). Simultaneously, he became aware of the large amount of research on prescribed fire in BC forests, with broadcast burning being the main method of site preparation across much of the province at that time.
Sanborn undertook various projects in this area of research:
- UBC Postdoctoral Project on effects of prescribed fire on sulphur in forest soils (1988-90)
- Cluculz retrospective study (E.P. 886.10) with the BC Ministry of Forests and UNBC
- Sulphur stable isotope tracer study (E.P. 886.15) with the BC Ministry of Forests and UNBC
During Dr. Sanborn's years with the Ministry of Forests research program (1991-2002), he worked on forest fertilization research with silviculturist Rob Brockley (retired; formerly at Kalamalka Research Station, Vernon, BC). Brockley’s work in the 1980s and early 1990s had documented the widespread pattern of sulphur deficiencies across the BC interior, and the superior response of managed stands to fertilization treatments involving sulphur (S) and nitrogen (N) rather than nitrogen alone.
To progress farther, different methods for understanding the fate of sulphur fertilizers in forests and soils were needed. Sanborn contacted the stable isotope group at the University of Calgary which had done important work on the fate of pollutant sulphur emitted by oil and gas extraction and processing in Alberta, using natural abundances of sulphur stable isotopes as a tracer. This was the beginning of a collaboration with Dr. Bernhard Mayer of the University of Calgary, and also with his German soil scientist colleague, Dr. Joerg Prietzel (Munich Technical University).
The research team engaged in the Cluculz retrospective study (E.P. 886.10) for the BC Ministry of Forests.
An ancillary project involved resampling (2002 - foliage, 2003 - soil) of a previously fertilized (1990) installation (E.P. 886.10) south of Cluculz Lake in order to compare the longer-term effects of different fertilizer sulphur forms on soil and foliage chemical properties. Results were published as a journal article and a Ministry of Forests Extension Note:
